My daughter has an '07 XC90 and just the last few days it starts violently shaking while going down the road. It doesn't matter at what speed she's going and it doesn't do it all the time. I was told to check the bushings. Any other ideas?
Thanks..

 

If it's while braking the rotors would be a good place to start.

If the tires are old, worn tires can do all sorts of funny things.

If not while braking it could be any number of the suspension/steering parts. I'd look at the lower control arms and tie rods first. Obviously this needs to be taken care of soon due to the potential danger of losing control.

A quick test is to jack the vehicle up so the tire if off the ground. Wiggle it with your hands at 12 and 6 o'clock and then at 3 and 9 o'clock.

Movement at 12 and 6 is usually ball joint related.

Movement at 3 and 9 is usually tie rod related.

 

I jacked it up and took off the tires and found my issue I believe. Both boots at the hubs were torn or open and the grease had slung all up in the wheel wells. Worst part of it all is the price to repair. I couldn't find the replacement axles anywhere, due to the VIN and the small window of platform that my car was manufactured in. I called everyone I found online and suggestions from my mechanic. Parts were $1,649.01. That really hurt the wallet, but I reckon safety has not price..Right? ha ha


Thanks for the help.

 

Ouch...if safety DOES have a price, you might have been getting close to it, LOL!

If you remember, post a followup to verify that fixed things. Might help someone else in the future.
